DELAYING CACHE STATE UPDATES IN NON-SPECULATIVE CACHE MEMORY IN PROCESSOR SYSTEM IN RESPONSE TO SPECULATIVE DATA REQUEST UNTIL SPECULATIVE DATA REQUEST BECOMES NON-SPECULATIVE Russian patent published in 2024 - IPC G06F12/802 G06F9/30 

FIELD: physics.

SUBSTANCE: invention relates to methods of managing cache memory of a computer system. Technical result is achieved due to the fact that the cache controller is configured to: select a SAR record in the SAR scheme, wherein the SAR record contains the instruction ID and the main data set; and in response to the fact that the received instruction ID in the fixation indicator indicates that the data request loading instruction is non-speculative, determine whether or not the received instruction ID is contained in the instruction ID entry in the SAR entry in the SAR scheme; and in response to determining that the received instruction ID is contained in the SAR record in the SAR scheme, updating the cache replacement state of the cache entry proper in the main data array corresponding to said index in the main data array entry associated with the target address of the data request in the SAR entry containing the received instruction ID.

EFFECT: faster operation of the system by reducing the occupied cache memory.
